“…In the past decades, several new pitviper species have been described from South America (Harvey 1994;Ferrarezzi & Freire 2001;Silva & Rodrigues 2008;Barbo et al 2012Barbo et al , 2016Carrasco et al 2019), and new discoveries seem likely to occur in the Andean Mountain Range (e.g., Esqueda et al 2005;Passos et al 2009;Rojas-Morales 2012). This vast territory harbors large regions of poorly explored terrain with diverse habitats, most of which have favorable conditions to house pitvipers, like the deep interandean valleys (Koch et al 2018).…”

We describe a new species of montane pitviper of the genus Bothrops from the Cordillera Oriental of the Central Andes, distributed from southern Peru to central Bolivia. The new species can be distinguished from its congeners by the characteristic combination of a dorsal body color pattern consisting of triangular or subtriangular dark brown dorsal blotches, paired dark brown parallel occipital stripes, a conspicuous dark brown postocular stripe, the presence of canthorostrals in some specimens, prelacunal fused or partially fused with second supralabial, one scale usually separating internasals, rostral trapezoidal, two canthals oval to rounded, similar size or slightly larger than internasals, three or four medial intercanthals, eight to twelve intersupraoculars, intercanthals and intersupraoculars keeled and frequently slightly keeled, supraoculars oval, one to three suboculars, two to three postoculars, loreal subtriangular, two to six prefoveals, subfoveals absent, two or none postfoveals, one or two scales between suboculars and fourth supralabial, seven or eight supralabials, nine or eleven infralabials, 23–25 middorsal scales, 189–195 ventrals in females and 182–190 in males, 48–58 subcaudals in females and 54–63 in males, exceptionally undivided. The new species is apparently restricted to areas within Andean montane forests that are less humid and devoid of large trees.

“…Species face the challenge of living and coexist in complex landscape mosaics that include original habitats, new environments, and urban and agricultural zones [11,12]. Regardless of the motivation, the desire to conserve reptiles and to better understand their ecology requires knowledge of their status, distribution, and factors that contribute to the decline or increase of their population [13].…”

Is the population of Crotalus durissus (Serpentes, Viperidae) expanding in Brazil?

Crotalus durissus are found from Mexico to northern Argentina in a highly disjunct distribution. According to some studies, this species is prone to occupy areas disturbed by human activities and floods comprise a plausible method of dispersal as inferred for some North American rattlesnakes. Based on the literature, it seems plausible that Crotalus durissus expanded their natural distribution in Brazil due to floods, but only in a few municipalities in Rio de Janeiro State. Data entries of Butantan Institute, in São Paulo, Brazil, from 1998 to 2012 show a declining tendency of snakes brought by donors. In addition, research shows no evidence of Crotalus durissus being an expanding species in the Brazilian territory.

“…There have been several endeavors to document the diversity of non-avian reptiles in Caldas (eastern flank of the Occidental Cordillera) and in both flanks of the Central Cordillera and the inter-Andean valleys formed by the Cauca and Magdalena rivers (Acosta-Galvis, 2009;Ramírez-Chaves et al, 2022), but the focus has concentrated on the middle valley of the Magdalena River (Flórez-Jaramillo & Barona-Cortés, 2016; Rojas-Morales et al, 2018), with relatively few contributions centered on localities of the Cauca River basin (Rojas-Morales, 2012;Rojas-Morales et al, 2014), which is also the case with the northern and western portions in Caldas, particularly along the borders of the departments of Antioquia and Risaralda (Ramírez-Chaves et al, 2022). While in recent years, the cords of non-avian reptiles of Caldas have increased, encompassing up to 112 species (Ramírez-Chaves et al, 2021;, there is still a need for updated and historical information on the local non-avian reptile fauna, which is relevant as a baseline for forthcoming diversity assessments and conservation plans.…”

Studying non-avian reptiles in the Colombian Andean region has encompassed various spatial scales and historical times. The knowledge of non-avian reptile diversity in the Department of Caldas (Central Andes; 7,888 sq. km. area; intricate geomorphology) has grown significantly in recent decades, especially in the areas to the east of the department within the Magdalena Valley and near Manizales, the capital city. Here, we consolidate the data from biological collections, literature, and unpublished research in a historical synopsis of the studies conducted in Caldas with an updated account of non-avian reptile species recorded in them. We found that the records of non-avian reptiles in Caldas trace back to pre-Columbian and colonial times, with specimens in biological collections dating back over a century. This non-avian reptile richness comprises 126 species grouped in 69 genera, 25 families, and three orders. Three out of the 27 municipalities in Caldas (La Merced, Marulanda, and Marquetalia) lack validated specimens or records. Furthermore, there is limited information regarding protected areas such as Los Nevados and Selva de Florencia National Natural Parks, which demands further research to unravel the diversity patterns of this biological group within this specific segment of the Andes.
